The way to improve the leg is to practice vital capacity and improve the heart function. It can be said that the development of thigh muscles is directly proportional to vital capacity and heart function.
The deeper you squat, the more vital capacity you need and the stronger your heart function. Obviously, the lung capacity of squatting is greater than that of squatting.
Heavy-shoulder vertical squat requires more vital capacity and stronger heart function than other squats (hard-pull dumbbell squat, two-handed barbell squat, oblique squat). Because the barbell is pressed vertically above the heart.
The main reason why pedaling is larger than squatting is that the vital capacity required by pedaling is small, which is about 1/2 of squatting, and the pressure on the heart is also small, so the pedaling amount is twice that of squatting. However, the knee joint moves a long distance when kicking, which affects the force on the thigh. When lying flat, the elbow joint moves a long distance, which affects the stress on the upper arm. So push-ups are similar to horizontal push-ups.
Squat lifts are similar to parallel bars, arm flexion and extension or push-ups. The quadriceps femoris and triceps brachii of the upper arm bear the same force, because there is less movement of knee joint and elbow joint.
Is it inappropriate for people with poor cardiopulmonary function to practice squats? No, because the central lung function is strengthened in the process of practicing squat.
Conclusion The difficulty of leg training lies in squat. If you dare to practice squats, it is not difficult to practice your legs.
Leg flexion and extension and leg bending are good leg exercises, and the principle is the same as arm flexion and extension and arm bending.
Therefore, friends who need thighs to lose weight don't have to worry. Practicing leg flexion and extension and leg bending can effectively solve the problem.
"Squat with load", also known as "squat with load", is one of the most complicated movements in bodybuilding and also an action in weightlifting competition. "Squat with load" has a strong stimulation to the whole lower limbs and trunk, and can exercise quadriceps femoris (rectus femoris, midthigh, lateral thigh and medial thigh), gluteus maximus, biceps femoris, semitendinosus and semimembranous muscle, and also has a strong effect on erector spinae, piriformis, adductor, gluteus medius, gluteus minimus and calf muscle. In addition, "weight-bearing squat" has a positive impact on a series of physiological and biochemical reactions such as cardiopulmonary function, nerve regulation and hormone secretion, so practicing "weight-bearing squat" is a compulsory course for professional athletes and amateur bodybuilders.
"Barbell Squat" belongs to "weight squat". Barbell squat is one of the basic movements to develop lower limb muscles. However, some beginners will feel uncomfortable after practicing squat, such as back pain, tenderness and redness behind the neck, even if the shoulder and neck are padded with sponge. Why is this happening? The main reason is incorrect movements, especially improper placement of barbells. Improper and unsafe barbell placement will not only distract the attention of practice, affect the effect, but also easily cause sports injuries. Statistics show that the barbell slipping off, or tilting, swinging and shaking left and right when squatting, is an important cause of low back pain. Because the barbell is heavy, it is difficult to control when squatting.
